T 0 all whom t may concern.'

Be it known that I, JOSEPH Persan, a citizen of the United States, and a resident of Mount Vernon, in the county of Vestchester and State of New York, have invented certain new and useful Improvements in Heading-Machines, of which the following is a specification.

The present invention relates generally to a heading machine such as is used in uniting can bodies and covers,l and has for its main object such reorganization of the parts as will reduce a simple and efficient structure in w ich the bodies and covers are associated before they are united, and in which the contents of a can body is compressed against the cover that is to be united with that particular can body. i

The invention consists of the general arrangement of the parts hereinafter set forth and also of the particular features of construction that enter into that organization.

lin the accompanying drawings the invention is disclosed in a concrete and preferred form in which changes of constructions may be made without departing from the scope of the invention.

lin these drawings:

Figure 1 is a front elevation of a machine embodying the invention and showing one can body on the heading or 'seeming plunger while the latter is elevated and another can being transferred from the can body conveyer to the topping or transfer plunger while the latter is in its lowered position.

Fig. 2 is a View looking in the direction of arrow 2 of F ig. 1 with parts removed and in section.

Fig. 3 is a plan view of Fig. 1.

Fig. i is a view of the elements Shown at the right hand end of Fig. 1, with parts removed, the heading or seaming plunger being lowered and the topping or transfer plunger elevated.

1F ig. 6 is a sectionalplan view of the parts relating to the can body and cover feeding means substantially on line 6 6 of Fig. 5. F Fig. 7 is a sectional View on line 7-7 of g. 8 is a lsectional detail view on line @-8 of Fig. 3.

Fig. 9 is a diagrammatic view of the action of the can body and cover feeding means. l F 1g. 10 is a diagrammatic View of the timing of the elevation of the can body on the topping or transfer plunger.

1 indicates a framework of any suitable yconstruction mounting a heading or seaming mechanism 2 that is adjustable by means of a handwheel 3 in a well known manner. The seaming members 4 are of the character cominonly known as double seaming members and may take 'such form as is desirable. An approved form, suitable for use in a machine of this character, is shown in application Ser. No. 180,270.

Directly under the seaming head 2 is a seaming plunger and adjacent thereto and in advance thereof, with respect to the direction of movement of the cans through the machine, iS a. topping or transfer plunger 6. The seeming plunger 5 is carried by a. spindle 7 supported by bearings 8 and 9 and actuated from a cam 10 (F ig. 2) by means of a cam lever 11 pivoted at 1.2 and having a. roller 13 engaging said cam 10 and having also a bifurcated member 11i (Fig. 4f) that engages spindle 7, in a known manner, to lift and lower piunger 5, the two positions of said piunger being indicated respectively in lFigs. 1 and 4c. rlihe top-ping or transfer plunger 6 is carried by a sleeve 15, mounted loosely on spindle 7, and is actuated from a cam 16 by means ota lever 17 pivoted at 18 and having a roller 19 engaging cam 16 and having a bifurcated member 20 that engages sleeve 15 to raise and lower piunger t3, the two positions being indicated respectively in 1F igs. a and 1. 1t will be observed that cams 10 and 16 act oppositely so that when plunger 5 is up, plunger 6 is down, and vice versa. lit will be seen from i that, when plunger 5 is down and plunger 6 up, the two plungers are on a level with each other so that a can body may be transferred from 6 to 5; and, it will also be seen, from Fig. 1, that when plunger 5 is up, the seeming operation takes place, and that when plunger t is down, it is on a levei with a raceway 21 so that a can body may be transferred from the rac/eway toplunger 6. The can bodies are movedl over raceway 21 in timed relation by projections 22 of a chain 23, saidcan body sliding on the raceway and the chain moving in a groove 24 and actuated by means ot sprockets 25 and 26. Flunger 6 has a central aperture 27 (best seen in Fig. 6) in line with which sprocket 25 is located and admits ot passage therethrough of projections 22 and chain 23, as will presently appear. Cams l0 and 16 are mounted on an upright cam shatt a cover therethrough as Well beforeas after.

seaming. The cover magazine 36 is located above the path of the can bodies and in ad vance, with respect to the direction of movement of the can bodies through the machine, of the topping orl transfer plunger 6 and in a straight line with it.

A gndeway for the covers from magazine 36 to the seaming head is provided by the following means. Carried on the underside of the plate 33 (Figs. 5 and 6) are a plurality of ledge members 37, 38, 39, 40 and 4l. rl`he members 37 and 38 are directly beneath the cover magazine 36 and, in effect, constitute .a part of it since the lowermost cover 42 rests on them. llt will be observed, however, that while these ledge members limit downward movement of the cover,

stack, they admit of lengthwise movementot the lowermost cover out of the plane of the magazine,that is, covers may be moved to the right in Fig. 6. rlfhe ledge member 39 is located adjacent one side of' the topping plunger 6; and adjacent the other side of said plunger is a cover detector consisting ot a lever 43 mounted on a rockshatt 44 and forming part of the guideway for the cover and to this'end, having a ledge 45, as shown. rlhe members 40 andv4l are located adjacent to seaming plunger 5 but, as will presently appear, these members 'may be dispensed `with. rl`he cover magazine 36 .consists here of a hopper 46 and four upright posts 47.

The cover detector 43 is normally held in.

the position shown in Fig. 6 by the passing covers and, when `so held, maintains rock'- shaft 44 in such position that the fast clutch member 48 (Fig. 5). will bein engagementv with the loose clutch member 49. rlhis is done throu h the instrumentality of a lever 50 (Fig. l and a link 51 (Fig. 5) .connected to a bell crank 52 provided with a biturcated portion 53 that engagesthe fast clutch member 48. lt a cover is absent, a spring 54 acts upon bell vcrank 52`to separate the clutch members 48 and 49. The sprocket 25 that drives the can chain 23 is carried by a stud shatt 55, on one end of which is a marcar bevel gear 56 `meshing with a bevel gear 57 on the loose clutch member 49. llt will theret'ore be understood that as long as covers are passing and hold detector 43 in proper position, clutch members 48 and 49 will be in engagement and can body chain 23 will continue to Y.teed a can body at regular intervals but that when a cover is missing, the can body teed will cease.

The feeding of the covers is controlled by the passage or the can bodies in the :following manner A can body detector 58 (Figs. l and 6) vis mounted on an larm 59 carried by a rockshatt 60. Mounted on this rockshaft is an arm 61 (Figs. l3, 6 and 5) that is provided atits outer end with a stud 62 engaging a separating knife 63. rlhe stud passes through a slot 64 in a cam slide 65, and knife 63 moves in .guides 66 and passes through plate 33 into the cover magazine at a' lpoint pist above the ledge member 37. The cam slide 65 has a roller 67 that engages in a cam 68. rThe detector 58 projects slightly into the path of the can. bodies, and, whenevera can body passes, said vdetector is moved outwardly to a-n extent sufficient to cause roclrshaft 60 to actuate arm '61 and thereby cause the latter to withdraw lmife 63 from the cover magazine so that a cover will drop -in position on ledges 37 and 3 8. Rotation of the cam 68 will thereafter actuate cam slide 65 which, in turn, will engage stud 62 and thereby movek knife v63 and cause thel latter to enter the cover magazine between the lowermost cover and the one next adjacent. @ther means, to be presently described, then removes the lowermostcover from the magazine. ln, case no can body passes,fit lis evident that `roclrshaft 60. is lnot actuated and that knife 63`is not withdrawn from the stack; and, that consequently, no cover will drop on .ledge 37. The action ofcam 68 is, under these circumstances idle because, when cam slide 65 is actuated, stud 62, on account of its position and the vpresence of slot'64, will not be moved'. y

69 indicates a double mold for shitting the can body and cover. rlhis mold consists ot' a ``plurality ot pockets,-here two, 70 and 7 1`,- mounted on a. carrying member 7 2. 73 and 74 are twogears rotating in the same direction andl receiving motion from gear 75 on cam shaft 28. Gears 73 and 74 carry crank pins 76 and 77 which are provided with shoes 78 that slide in slots 79 and 80 of "the carrying member72. 81 is a guidev or cam slot in bracket 32 into which extends a roller 82 mounted on the carrying member. The pocket 70 is provided with ledges 83 (Figs. 4, 5 and 6) that engage the lowermost cover inthe cover magazine and, moving it olf the ledges 37 and 38, slide it into position on ledges 39 and 45. The pocket 7l takes the can body with a cover inposition and moves it from plunger 6 onto plunger 5 removing, atthe same time, a can from plunger 5 out of the machine.

84 is a rotatable dial (Figs. 3, 7 and 8) that receives motion by means of bevel gears 85 and 86 from a shaft 87 carrying the sprocket 26 of the can 'body chain. Arranged above this dial is an outer stationary guide wall 88 that terminates in the straight guide 89 adjacent one side of can body chain 23 and an inner stationary guide wall 90 that terminates in a straight guide 91 adjacent the other side of the can body chain. It will be noted that the dial is closely adjacent the can body raceway21, and that the latter is cut away at one point 92 to permit the dial to bring the can bodies into line with projections 22 of the can body chain. Adjacent the dial is also a conveyer 93 for feeding can bodies from a suitable source, such 4as a filling machine, to the dial. The outer periphery of the dial is provided Vwith a plurality of notches 94 spaced apart a distance equal to the diameter of a can body, or substantially so. Pivotally supported adjacent each notch is a counterweighted pro-vl jection 95 that normally' projects above the surface of the dial.' Located beneath the dial is a stationary cam 96 that engages with each projection 95 as it arrives at the pointl Where conveyer 93 is located, thereby de pressing said projection. If a can body comes over one of the notches 94, the projection 95 will remain in its depressed position after it leaves cam 96 butwhen other can bodies coming from conveyer 93, have crowded the first can body a given distance, projection 95 will Ilise through its notch and act as a spacing member between can bodies and will thereafter advance the can body between walls 88 and 90 until it reaches can body chain 23. Y

The operation of the machine is as follows: The can' bodies are delivered in the manner described by conveyer 93 to dial 84 and thence to raceway 21 where a can body is thenv advanced by the can body chain in timed relation until it arrives adjacent plun` ger 6. At this moment, said plunger is in its lowermost position which is on a level with raceway 21. As projection 22 continues to push the can body, the latter will gradually-be seated on plunger 6 and, when it has moved over on said plunger a given distance, the plunger rises, projection 22 meanwhile continuing to push'the can body until it is in proper position on said plunger. Mean` jwhile., a cover has been moved by ledges 83 `,of pocket 70 from ledges 97 and 38 to the yledges 39 andl 45'and will be in position in line with the canbody being raised by the plunger 6. The result is .that the contents of the canbody is crowded down by the cover as the can body presses the latter against plate 33. The pocket 71 now grasps member 72 will move in a curved the can body and moves it from plunger 6 to plunger 5 which latter, at this moment, is in its lowermost position so that the two p ungers are on the same level. The movement of the can body carries the cover with it which is brought from the ledges 39 and 45 ontothe ledges 40 and 41. The ledges 40 and 41 are not necessary, but may be used if desired, as the cover is in position and has partly entered the mouth of the can body before the latter is moved.' Plunger 5 now rises and the seaming operation takes place, after which plunger 5 descends. It will be understood that while the can body and cover are being moved from plunger 6 to plunger 5, another cover is being movedV from the cover magazine to ledges 3 9 and 45 and that while the seaming operation takes place another can body is being moved from raceway 21 to plunger 5. It a can body is missing, detector 58 prevents the feeding of a cover, and if a cover is missing` detector 43 stops the feeding of can bodies by uncoupling clutch members 48 and 49 and thereby stopping the movement of chain 23. It will also be observed that when chain 23 ceases to move, sprocket 26 also stops and therefore dial y84 is no longerrotated.

The action of the double mold 69 is pe` culiar.4 Considering the position shown in Fig. 6 as denoting the beginning and the end of a cycle of movements of the carrying member-72, the direction of rotation being as indicated by the arrows, then during the first 900 of the crank movement, carrying path away from the can body and cover. During the next 90, shoes 78 of saidcranks will traverse slots 79 and 80 and th carrying member 72 will move to the left in a straight line, roller 82 acting against the straight surface 99 of cam guide 81. The parts will now occupy the position shown in Fig. 9. During the third quarter of revolution, the mem ber 72 moves toward the cover and can body in a curved path and during the remaining 90, member 72 will move in a straight path to the right on account of surface 102. When the cranks have rotated about 224, the left hand ledge 83 of pocket 70 strikes the cover held on ledges 37 and 38 and, at about the same time, the left hand horn of pocket 71 strikes the can body on plunger 6 as it is being moved by projection 22 of the can body chain. At this moment, the carrying member is moving to the right at substantially the chain 23. From this point on, however, member 72, due to the crank movement, gains in speed and the speed of the can body is therefore accelerated to such extent that the kcan body will be moved away from projecsaine speed as that nof continues until the cranks have rotated 27 0 when the movement is decelerated until the can body reaches, as it does at 360, its proper position on seeming plunger 5. At that time, the can body is practically at a stand still and pocket Il now disengages the can body. This action is plotted on the line of Fig. 9 Where it will be seen 'that the can body advances, while under the influence of can body chain 23, equal distances in equal periods of time and that, when it reaches the position indicated by 224, pocket 7l becomes effective and accelerates, and then decelerates, themovement of the can body as indicated by the unequal spacing between 224 and 86()O on line m. The advantage of this resides in the fact that the can body is moved gently so that its contents are not spilled. 'lt will be further understood that while the can body is being moved onto plunger 6 by means of chain 23, said plunger will rise. rllhe relation between these movements'is shown in Fig. 10 where it is seen that while the center line y of the can body moves from 140o to 224, as measured by the rotation of the cranks, the plunger rises, as indicated by the levels a of Fig. 10, so that at 224 .plunger 6 iscompletely elevated and the can body is in alinement with the cover .that is held by ledges 39 and 45.

rl`he movement of the can body under'wthe influence of the mold is duplicated inthe movement of the cover from ledges `37 rand 38 to ledges 39 and45. The cover is first moved slowly and then more quickly andis then gradually slowed down to. a state of` rest. It will be understood that in this man; ner, the cover reaches its position in line with the topping plunger 6 before the can body that is being moved by the chain is centered on said plunger.

The chief advantages of this machine are that the structure is compact; the handling of can bodies and covers simple and reliable; the topping of the contents of the can body is effected just prior to seaming so that-there is not sufficient time for it to work out again; and the topping of the contents is effected, not by an independent member, but by the cover of the can body.
